One of the major channels of the spinal cord is the spinothalamic tract; a sensory pathway. It conveys nerve impulses for sensing pain, warmth, coolness, itching, tickling, deep pressure, and crude touch. (Tortora, 2014-01-22, p. 461). Based on that description and as the name implies, information will travel from the region of stimulation on the skin to the CNS, ultimately landing at its destination at the thalamus; thus, making it an ascending pathway. This pathway is further divided into three levels of neurons for transmission:
The first level is where the sensation is translated into an electrical impulse from pseudounipolar neurons branching from the skin leading to the dorsal root ganglion where its axons synapses with the neuron at
